Welcome to find support for water protection!

Welcome to finding information, examples and practical tips for water protection!

Tools for water protection is a web-based toolbox providing support for implementing water protection actions at local level. It is designed for professionals and experts who do concrete work, strategic planning or make decisions on water protection in cities, municipalities, companies, NGOs or other organisations.

The Toolbox provides information and tools that assist with water protection. In addition to practical tips, tools and background information, in the Bank of Actions you can browse actions that local organisations have already implemented for the protection of local waters and the Baltic Sea – and you can also share your organisation’s own actions!

This site was established in 2015 by the EU Life+ funded project CITYWATER, in collaboration with the Baltic Sea Challenge. The first tools are based on the results of the CITYWATER project. The site is now managed and updated by the Baltic Sea Challenge. More tools and actions are needed – please contact us and tell us about your ideas!

Reconstruction of Lepiku water course

Actor: Tallinn City   ●   Year: 2015   ●   Address: Tallinn Botanic Garden, Kloostrimetsa tee, Tallinna, Viro

A reconstruction of the Lepiku water course in the Tallinn Botanic Garden was realized in order to improve the quality of rain and melting water and protect the Pirita river.


Lepiku water course runs through Tallinn Botanic Garden, collecting rain and melting water from the surrounding area before entering the Pirita river, which is a Natura 2000 site. Recent residential development in the Lepiku area has increased the amount of water entering the Lepiku water course. This development has had a negative impact on water quality. Furthermore, the original limestone walls in the water course had collapsed and the riverbed and culverts were stocked with sediments. Especially the solids in the water were of concern, because they contain nutrients, heavy metals and other harmful substances.


The reconstruction aimed at a natural purification process which aims to decrease the amount of particles in the water. Meandering of the creek, shallow thresholds on the bottom of the course and extended flooding areas were used to retain water flow and increase sediment settlement. Furthermore, solids are filtered from the water by the wetland vegetation on the sides and the bottom of the course. To prevent erosion, the walls of the water course are lined with limestone.

Background information

The reconstruction was realised in EU Life+ programme co-financed project CITYWATER.
